MOP WITH WRINGER ATTACHMENT I Filed Nov/26. 1928 M419 INVENTOR BY WW HISA TTORNEY Patented Nov. 12, i929 UNITED STATES HARRY HERTZBERG, OFBROOKLYN, NEW YORK 11101 WITH WRINGER ATTACHMENT Application filedNovember 26, 1928.

This invention relates to wringing attachments for mops, and its mainobject is to provide simple means attachable to the handle of any commonmop for squeezing the water out of mops of various types.

It is another object of the invention to pro-.

vide a wringer which can be attached'to the handle of any ordinary mopin a few seconds,

which does not require the mop to be of any special construction.

It is a further object of the invention to provide a wringer which isapplicable to mops of the knob or deck mop type.

WVith the foregoing and other objects in View as will appear in thedescription which follows, the invention resides in the combination andarrangement of parts and in the detail of construction hereinafterdescribed and claimed.

In the accompanying drawing forming part of this specification Fig. 1shows in a perspective view my wringing attachment in operating positionon a deck mop when squeezing water out of the mop.

Fig. 2 shows the wringer attached to the mop stick but removed from themop while the mop is in use.

Corresponding parts in Figs. 1 and 2 are 0 numbered alike, and thesenumbers are referrred to in the following description.

Referring to Fig. 2 of the drawing, 10 is a mop of the deck-mop typeattached to a mop stick 11. Mops of this type consist of a bunch of mopcords of equal length, folded upon themselves at their centers which aretied into a knob suitably connected to the lower end of mop stick 11.Below this knob the mop cords form a tuft of substantially circularcrosssection. My wringer attachment 1 1 is slipped upon stick 11 fromits free end. A pin or screw 12 is then inserted into mop stick 11 asuitable distance from its free end. My wringer 14 consists of a singlepiece of metalhe rod which is bent upon itself at its center and thentwisted to form a double helix 13. When the wringer is not in use thehelical coil 13 is turned to engage pin 12 which holds the wringer inthe position of Fig. 2. The two parts of rod 14: which extend from thelow- Serial No. 321,924.

er end of helix 13 are bent as shown to form the vertical guides 18 and19 extending lengthwise parallel to mop stick 11. At the extremities ofthese guides in a plane normal to the mop stick 11, the jaws 15 and 16are formed. Each jaw consists of two legs which form an anglewith eachother the apex of which may lean against mop stick 11. The rod of whichthese legs are made is bent upon itself at the end ofeach leg for itsreinforcement. A ring or hoop 17 is slidably mounted upon the guides 18and 19 which are bent. outwardly towards their lowerends, and as ring 17is moved downward towards the jaws 15l6, these jaws are pressed closertogether, thereby effecting a clamping action for pressing the jawsagainst mop stick 11.

When the wringing attachment is so clamped on the mop stick the mop canbe freely and conveniently used for mopping floors and the like.

When the attachment is to be used for wringing the mop, ring 17 isshifted to the upper end of guides 18 and 19 which releases jaws 1516from mop stick 11 and they separate to the dotted position of Fig. 2;helical coil 13 is released from pin 12 by twisting wringer 141 on stick11, jaws 15-1'6 can then be moved downward and pass over knob 10" of mop10 to the neck portion 10 when in this position ring 17 is againmoveddownward on guides 18-19 for clamping the mop materialbetween jaws1516.

As the wringer is also gradually turned on the mop stick andsimultaneously shifted towards the lower end of the, mop, the mop cordsare twisted and the water is effectively removed from the mop. Thepressure on the mop 10 is then released by moving hoop 17 upward; thejaws 1516, thus allowed to spread, are moved up over the head of theInop 10 and after diminishing the spread of the jaws again by movinghoop 17 down, the wringer is twisted clockwise around the mop stick 11until the spiral 13 engages pin 12 and is thereby held in place.

' It will appear clearly from the foregoing description that thiswringer is a very useful and efficient device, that it consists of onlytwo parts the construction of which is extremely simple.

It is of particular advantage that the wringer may be applied to anyordinary deck mop, by slipping it over the mop stick and inserting pin12 without the slightest alteration to the mop itself, and that it maybeplaced on a new mop when an' old one is worn out.

IIowever, while the preferred form of my I invention has been describedit is to be understood that such modifications may bemade in thearrangement of parts and in thecon'struction of minor details as maycome within the scope and spirit of the'invent'ion as claimed.

What I claim as new and desire to secure by Letters Patent is:

1. The combination with a mop liaiidle'of mop material forming a knoband a tuft at the end of said mop handle, wringingmeans slidably mountedon said handle, comprising a pair of jaws forming together a polygonsurroundin said tuft and means for contracting all sides of said polygontowards its center to press against the material ofsaid tuft and fortwisting the same.

2. The combination with a mop handle (if 'mop material attached thereto,wringing means slidably mounted on said handle, said meanscompri sing apair of angular jaws forming together rectangle -to embrace saidmaterial for wringing the same and means for moving said angular jawsdiagonally of the said rectangle towards the-mop axis.

'3. The combination with a mop han'dle and a mop head, of means forwringing said inop head, said means comprising a guide 's lidablymounted on said handle, apair of guide rods extending parallel tosaid'handle, "a jaw having two legsf-orming an angle with each otherat'the lower end of each guide rod and means engaging said guiderods forpressing' b'oth legs of each jaw'against-said mop head to pressaplurality of opposite sides of said material towards the mop axis. I

4. The combination with a mop and mo'p stick attached thereto, of a pairof jaws movable towards each other forming a parallelogram around saidmop, a pair of guidesparalle l to-said mop stick attached to saidjaws,means for'sliding said jawsalongsaid mop stick anda ring enclosing saidguides for Varying the clamping pressure exerted by said jaws bycontractingsaid parallelogram uniformly towards its center.

5. The combination with'a mop head, and a handle attached thereto, of awringer comprising a metallic frame pair of'jaws at the extremities ofsaid frame each jaw being formed to partly surround said mop head andadapted to clamp and to twist said mop material, guiding inea'ns forsliding said jaws along said handle, consisting of a plurality of barsholding said jaws at their lower end, and

a helical coil formed integral with said bars at their upper end mountedon said handle.

6. The combination with a mop handle of mop cords joined to the end ofsaid handle forming a tuft thereon of substantially circularcross-section, a frame slidably mounted on said handle, means to guidesaid frame to slide and -i'otzite on saidhandl'e, a p air of jaws at thelower end of said frame bent to completely embrace said tuft, each jawforming meansto pressiadially difierent sides of said tuftfongatheringsaid mop cords to the mop axis and for twisting the same.

7; A wringing "device adapted to be attached to a mop handle consistingof a single rod of'metalbent to form a frame having at its upper end atubular portion for encircling said handlef a pair of resilient-guiderods to extend longitudinallyof said handle and a pair of complementaryjaws atth'e lower end of said guide bar'sstra'ddling"said h'an dle inopposite direction, all parts of said fram being formed integral witheach other and of said rod, and a ring'surroundingsaid frame forclosingsaid jaws.
